Brake Options for 1957-68 Cadillac Models

Cadillac brake fitment changes at several points between 1957 and 1968, and those year breaks shape the collection more than any single brake configuration. The 1957-60 cars begin with dedicated front disc options, including a Wilwood Dynalite system, while 1959-60 models also have their own complete power disc conversion.

In the 1960s, the combinations change. A front disc system spans 1961-68 applications, but complete power conversions divide into separate 1961-62 and 1963-68 packages, reflecting differences that developed even within the same generation of full-size Cadillacs.

Behind those vehicle-specific conversions is a much broader hydraulic selection. 1-inch and 1-1/8-inch bore master cylinders sit alongside POL, Wilwood, and Baer aluminum designs, giving each brake system its own approach to fluid volume and pedal response.

Combination valves, proportioning hardware, distribution blocks, stainless hoses, and fittings connect those pieces into the rest of the system. The result is a collection shaped first by Cadillac’s changing chassis years, then by how far the braking system itself has been upgraded.

FAQ

How do I choose the right brake parts for my 1957-68 Cadillac?

Begin with the exact model year because POL divides several Cadillac brake conversions into specific year ranges. Then identify whether the car currently has drum or disc brakes, manual or power assist, the master cylinder setup, and the wheels being used. Previous modifications should also be checked before choosing parts based only on the original factory configuration.

Can I convert a 1957-60 Cadillac to front disc brakes?

Yes. POL offers a dedicated 1957-60 Cadillac front disc brake conversion as well as a Wilwood Dynalite Pro Series front brake kit for the same year range. For 1959-60 cars, a complete front power disc brake conversion is another option. Compare the components included, hydraulic requirements, and wheel fitment before deciding which system suits the car.

Which disc brake conversion fits a 1961-68 Cadillac?

POL lists a front disc brake conversion covering 1961-68 Cadillacs. Power-assisted packages are divided more specifically, with one conversion for 1961-62 cars and another for 1963-68 applications. Confirm the exact year before choosing between the standard disc conversion and a complete power disc setup.

What is the difference between a standard and power disc brake conversion?

A standard front disc conversion focuses on changing the front wheel brakes to discs, while a power disc package also addresses power assistance and other system components included with that particular kit. POL lists both types for selected Cadillac years. Check each product's contents carefully because the components supplied vary between conversions.

What master cylinder should I use with my Cadillac disc brakes?

Choose the master cylinder according to the complete brake configuration and whether the brakes are manual or power assisted. This collection includes 1-inch and 1-1/8-inch bore GM-style master cylinders, POL aluminum designs, Wilwood tandem master cylinders, Baer Remaster units, and packages paired with proportioning valves. Bore size, pedal setup, brake assist, and caliper requirements should all be considered.

Do I need a proportioning valve after converting my Cadillac to disc brakes?

The hydraulic controls need to match the brake configuration being used. POL carries fixed combination valves, adjustable proportioning valves, side-mount and under-mount kits, distribution blocks, fittings, and related components within the Cadillac range. The appropriate setup depends on whether the car uses disc/drum or disc/disc brakes and how the master cylinder is configured.

What should I check before ordering a Cadillac disc brake conversion?

Confirm the exact model year, existing front and rear brakes, master cylinder, manual or power assist, wheel size and clearance, and any components that have previously been changed. Pay particular attention to POL's year divisions, such as 1957-60, 1959-60, 1961-62, 1961-68, and 1963-68, because similarly named Cadillac conversions are not necessarily interchangeable.
